' TRICYCLE.

SPECIFICATION forming part of Letters Patent N 0. 461,207, dated October 13, 1891.

Application filed April 27, l89l- Serial No. 390,551- (No model.) I

To all whom it may concern..- Be it known that I, FRANK J. KESSLER, Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Tricycles; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures-of reference marked thereon,

which form part of this specification.

My invention relates to tricycles, and has for its object to provide an inexpensive, strong, and durable frame composed of but few parts, thereby reducing the cost of manufacture to a minimum.

A further object is to provide a simple, inexpensive, and flexible connection of pitmen and trundle.

A further object is to provide a convenient attachment for the seat.

The invention consists in the parts and com: bination of parts hereinafter described, and pointed out in the claims.

In the drawings, Figure l isa perspective view of a tricycle constructed in accordance with my invention. Fig. 2 is a detail view of the frame. Fig. 3 is a side elevation of the frame, showing the mode of attaching the seat thereon. Fig. 4 is a sectional detail view on lines w m, Fig. 5, showing the means employed for journaling the front pitmen to the frame; Fig. 5 is a detail view of a portion of the frame, showing the pitmen attached thereto. Fig. 6 is a side elevation of one of the pitmen.

1 designates the spine, connected with the frame 2 by means of a coupling 3, the front end of the spine being provided with a bearing 4 for the reception of the steering-fork 5, to which the handle-bar 6 is secured.

7 designates a tubular T or cross bar secured to the spine for a purpose hereinafter stated.

8 designates boxes, into which the axle?) is journaled, the wheels 10 being properly se- Acured upon the outer ends thereof. Intermediate boxes 8 the axle is formed into a du plex-crank shaft, there being pitmen 11 and 12 secured upon each crank 13 and 14, respectively, of the shaft, preferably by means of straps 15, which embrace the rear portion of the crank and hold the boxing 16 of the pitmen closely assembled to prevent looseness and rattling of the parts.

17 designates the pedal, formed out of two depending lugs 18, to which the two sections of pitmen are pivotally secured by means of pins 19 passing through the bifurcated ends of the pitman and the intermediate lug of the pedal, whereby the pedal and pitman may have an easy pivotal movement when raised or depressed.

The forward end 20'of each pitman 11 is bent at an angle to the body of the pitman to cause the same to enter the tubular T or cross bar 7 and is threaded to allow of running a nut 21 thereon, the T being chambered out to receive the nuts and hold the same from turning.

Each box 8 is formed with an upwardlyextending tubular boss 22 and a like boss 23 at right angles thereto, the frame 2 being secured at each in one of the bosses 23 either by being threaded and screwed therein or by means of a pin or bolt.

24 designates seat-support, formed with a vertical standard 25, the lower end of which enters the tubular boss 22 of box 8 and is secured-therein either by being threaded and screwed therein or by means of transverse pins passing through the boss and standard.

At the upper end of standard 25 is formed a T 26, slightly curved at the center, whereby the ends 27 project therefrom in horizontal relation and are perforated, as at 28, tdYeceive bolts 29, which are passed through the frame of seat -30 and intermediate rubber buffers 31, whereby the seat is not only secured to the seat-support, but has a slight spring due to the interposed rubber springs.

From the above description it will be s en that I reduce the parts to a minimum, as by casting the boxes 8 to also serve as a fastene ing for the frame and seat-support, and also by forming the seat-support and standard of one piece, as well as journaling the forward end of the pitman in the T or cross bar, I am enabled to cast all the parts except the spine and frame 2, which may be made of ordinary gas-pipe.

By my invention of pedal and pitmen I simplify the construction and cheapen the product, as well as render the same pivotal and free from torsional strain.

What I claim is 1. In a tricycle, crank-axle boxes formed with duplex tubular extensions at an angle from the axis, a frame secured in one set of extensions, and seat-supports secured in the remaining extension.

2. In a tricycle, a frame comprising a spine, a frame secured thereto, boxes formed With horizontally-projecting' tubular projections, with which the frame is secured, vertical tubular projections upon the box, and standards secured therein, formed with T-heads, upon which the seat is supported."

3. In a tricycle, pedals formed with duplex depending lugs, in combination with two-part pitmen formed with bifurcated end portions to receive the lugs, and transverse pins passing through the lugs and pitmen, Whereby' the pedal and pitmen form a pivotal movement.

4. In a tricycle, a spine, in combination with a T or cross bar formed with tubular ends and chambers, nuts within the chambers,

and pitmen formed with angular threaded FRANK J. KESSLER.
